The git repo for the FEG is in Fedora Hosted. I believe Nigel Jones turned it over to David Nalley. I'm checking to see if David can grant access for people to help with the guide. If so, it simply needs to be converted to the newer Publican standards, and we can publish it in a proper place on docs.fp.o. For now I put it up on my space and I'll fix the link appropriately.
